Class QuickStatReq

java.lang.Object
  |
  +--tapestry.patchwork.QuickStatReq

All Implemented Interfaces:

PatchMsg, QueueElementIF

public final class QuickStatReq

extends Object

implements QueueElementIF, PatchMsg

A QuickStatReq event can be sent by any stage to the Patchwork stage. It triggers the measurement of a set of nodes, but only for a small amount of time. After that amount of time has passed, a QuickStatResp is sent back with the results of the measurements.
